示例 example
示例1:制造热负荷传感器的方法Example 1: Method of manufacturing a thermal load sensor
在筒状的空的容器中制作热负荷传感器。将具有单体和交联剂的5毫米厚的一层未固化的聚二甲基硅氧烷(PDMS)预聚物倾倒到容器中。未固化的PDMS在凝胶点温度(90℃)下被固化成凝胶。石蜡被用作有机指示材料。石蜡被热成形为具有4毫米的直径和2毫米的高度的四个圆柱体。四个石蜡圆柱体被放置到固化的PDMS的中心处并且均等地间隔开。额外的5毫米的一层未固化的PDMS被倾倒到石蜡圆柱体上以完全覆盖石蜡圆柱体。未固化的PDMS在与先前的一层PDMS类似的条件下被固化。热负荷传感器的表面压印有用于热负荷度量的可视标记物。具有被PDMS封装剂包围的石蜡盘的热负荷传感器被从容器切割去除。热负荷传感器放置在80℃的热板上30分钟。石蜡扩散到PDMS基质中并且产生在包围石蜡的PDMS中被均匀间隔开的云状环。云状环绕着石蜡的位置形成同心环。观察到,随着传感器暴露于热的时间增加,石蜡的扩散程度增大并且因此同心环的数量也增加。可视标记物是从石蜡的位置向外延伸的线标记,线标记被校准以基于石蜡的扩散程度来指示暴露时间。因此,热负荷传感器可以检测热负荷,诸如如该示例中描述的暴露于高温的暴露时间。 Fabricate a thermal load sensor in a cylindrical empty container. A 5 mm thick layer of uncured polydimethylsiloxane (PDMS) prepolymer with monomer and crosslinker was poured into the container. Uncured PDMS is cured into a gel at the gel point temperature (90 °C). Paraffin was used as an organic indicator material. Paraffin was thermoformed into four cylinders with a diameter of 4 mm and a height of 2 mm. Four paraffin cylinders were placed into the center of the cured PDMS and equally spaced. An additional 5 mm layer of uncured PDMS was poured onto the paraffin cylinder to completely cover the paraffin cylinder. Uncured PDMS was cured under similar conditions to the previous layer of PDMS. The surface of the thermal load sensor is embossed with visual markers for thermal load measurement. A thermal load sensor with a paraffin disk surrounded by PDMS encapsulant was cut from the container. The heat load sensor was placed on a hot plate at 80°C for 30 minutes. The paraffin diffuses into the PDMS matrix and creates cloud-like rings that are evenly spaced in the PDMS surrounding the paraffin. Clouds form concentric rings around the location of the paraffin. It was observed that as the time the sensor was exposed to heat increased, the degree of paraffin diffusion and thus the number of concentric rings also increased. Visual markers are line markers extending outward from the location of the paraffin that are calibrated to indicate exposure time based on the degree of paraffin spread. Thus, a thermal load sensor can detect thermal loads, such as exposure time to high temperatures as described in this example.

传感器将被用于检测生物负荷。传感器将具有封装烷烃圆柱体的丙烯酸酯聚合物基质以及被布置为邻近烷烃圆柱体的过氧化氢的储存器。将在丙烯酸酯聚合物基质上邻近烷烃圆柱体的地方包括标志。标志将具有指示酵母污染物的风险的两个线标记,一条线将具有在其上方的词语‘低风险’,并且另一条线将距烷烃圆柱体更远且将具有在其上方的词语‘高风险’。传感器将被设计成检测周围环境中的酵母。传感器将被附接到一盒苹果。当环境中存在酵母时,过氧化氢将与酵母反应且释放热量。该热量将熔化石蜡,导致石蜡扩散到丙烯酸酯聚合物基质中。标志将被用于确定石蜡的扩散程度以判定在周围环境中检测到的酵母量是否已达到会污染苹果的水平。 Sensors will be used to detect bioburden. The sensor will have an acrylate polymer matrix encapsulating the alkane cylinder and a reservoir of hydrogen peroxide disposed adjacent to the alkane cylinder. A logo will be included adjacent to the alkane cylinder on the acrylate polymer matrix. The sign will have two line markings indicating the risk of yeast contamination, one line will have the word 'low risk' above it and the other line will be further from the alkane cylinder and will have the word 'high' above it risk'. The sensors will be designed to detect yeast in the surrounding environment. The sensor will be attached to a box of apples. When yeast is present in the environment, the hydrogen peroxide will react with the yeast and release heat. This heat will melt the paraffin, causing the paraffin to diffuse into the acrylate polymer matrix. Flags will be used to determine the extent of paraffin spread to determine whether yeast levels detected in the surrounding environment have reached levels that would contaminate the apples.

关于本文中基本上任何复数和/或单数术语的使用,本领域技术人员可以根据上下文和/或应用适当地从复数变换成单数和/或从单数变换成复数。为了清晰的目的,本文中明确地阐明了各单数/复数的置换。 With respect to the use of substantially any plural and/or singular term herein, those skilled in the art can switch from the plural to the singular and/or from the singular to the plural as appropriate depending on the context and/or application. For purposes of clarity, each singular/plural permutation is explicitly set forth herein.
本领域技术人员将理解,一般地,本文所使用的术语,尤其是随附权利要求(例如,随附权利要求的主体)中所使用的术语,通常意在为“开放式”术语(例如,术语“包括”应当解释为“包括但不限于”,术语“具有”应解释为“至少具有”,术语“包括”应解释为“包括但不限于”,等等)。本领域技术人员还理解,如果意图表达引导性权利要求记述项的具体数量,该意图将明确地记述在权利要求中,并且在不存在这种记述的情况下,不存在这样的意图。例如,为辅助理解,下面的随附权利要求可能包含了引导性短语“至少一个”和“一个或多个”的使用以引导权利要求记述项。然而,这种短语的使用不应解释为暗指不定冠词“一”或“一个”引导权利要求记述项将包含该所引导的权利要求记述项的任何特定权利要求局限于仅包含一个该记述项的实施例,即使当同一权利要求包括了引导性短语“一个或多个”或“至少一个”以及诸如“一”或“一个”的不定冠词(例如,“一”和/或“一个”应当解释为表示“至少一个”或“一个或多个”);这同样适用于对于用于引导权利要求记述项的定冠词的使用。另外,即使明确地记述了被引导的权利要求记述项的具体数量,本领域技术人员将理解到这些记述项应当解释为至少表示所记述的数量(例如,没有其它修饰语的裸记述“两个记述项”表示至少两个记述项或两个以上的记述项)。此外,在使用类似于“A、B和C等中的至少一个”的惯用法的那些实例中,通常这样的构造旨在表达本领域技术人员理解该惯用法的含义(例如,“具有A、B和C中的至少一个的系统”将包括但不限于仅具有A、仅具有B、仅具有C、具有A和B、具有A和C、具有B和C、和/或具有A、B和C等等的系统)。在使用类似于“A、B或C等中的至少一个”的惯用法的那些实例中,通常这样的构造旨在表达本领域技术人员理解该惯用法的含义(例如,“具有A、B或C中的至少一个的系统”将包括但不限于仅具有A、仅具有B、仅具有C、具有A和B、具有A和C、具有B和C、和/或具有A、B和C等等的系统)。本领域技术人员将进一步理解,呈现两个以上可选项的几乎任何分离词和/或短语,无论是在说明书、权利要求或附图中,都应理解为设想包括一项、任一项或两项的可能性。例如,术语“A或B”将理解为包括“A”或“B”或“A和B”的可能性。 Those skilled in the art will appreciate that terms used herein in general, and especially in the appended claims (e.g., the body of the appended claims), are generally intended to be "open-ended" terms (e.g., The term "comprising" shall be interpreted as "including but not limited to", the term "having" shall be interpreted as "having at least", the term "including" shall be interpreted as "including but not limited to", etc.). It will also be understood by those within the art that if a specific number of an introductory claim recitation is intended, that intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, use of this phrase should not be construed to imply that the indefinite article "a" or "an" introduces a claim recitation to limiting any particular claim containing the introduced claim recitation to containing only one of that recitation. even when the same claim includes the introductory phrase "one or more" or "at least one" and an indefinite article such as "a" or "an" (e.g., "a" and/or "a " should be construed to mean "at least one" or "one or more"); the same applies to the use of definite articles used to introduce claim recitations. In addition, even if the specific number of the introduced claim recitation items is explicitly recited, those skilled in the art will understand that these recitation items should be interpreted as at least indicating the recited number (for example, the bare recitation "two" without other modifiers A description item" means at least two description items or more than two description items). Furthermore, in those instances where a idiom similar to "at least one of A, B, and C, etc." is used, generally such constructions are intended to convey what those skilled in the art understand the idiom to mean (e.g., "has A, A system of at least one of B and C" will include, but is not limited to, having only A, only B, only C, having A and B, having A and C, having B and C, and/or having A, B, and C and other systems). In those instances where a idiom similar to "at least one of A, B, or C, etc." is used, generally such constructions are intended to convey the meaning that those skilled in the art understand the idiom (e.g., "having A, B, or A system of at least one of C" would include, but is not limited to, having only A, only B, only C, having A and B, having A and C, having B and C, and/or having A, B and C, etc. etc. system). Those skilled in the art will further appreciate that virtually any discrete word and/or phrase presenting two or more alternatives, whether in the specification, claims, or drawings, is to be understood as contemplated to include either, either, or both. item possibility. For example, the term "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
另外,在根据马库什组(Markushgroup)描述本公开的特征或方案的情况下,本领域技术人员将理解的是本公开也因此以马库什组的任何独立成员或成员的子组来描述。 Additionally, where features or aspects of the disclosure are described in terms of a Markush group, those skilled in the art will understand that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group .
本领域技术人员将理解的是,为了任何以及全部的目的,诸如在提供所撰写的说明书方面,本文所公开的全部范围也涵盖了任何和全部的可能的子范围及其子范围的组合。可以容易地认识到任何所列范围都充分地描述了同一范围并且使同一范围分解成至少均等的两半、三份、四份、五份、十份等等。作为非限制示例,本文所论述的每个范围可以容易地分解成下三分之一、中三分之一和上三分之一,等等。本领域技术人员还将理解的是,诸如“多达”、“至少”等所有的语言包括所记述的数量并且是指如上文所论述的随后可以分解成子范围的范围。最后,本领域技术人员将理解的是,范围包括每个独立的成员。因此,例如,具有1-3个单元的组是指具有1个、2个或3个单元的组。类似地,具有1-5个单元的组是指具有1个、2个、3个、4个、或5个单元的组,等等。 It will be understood by those skilled in the art that for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. It can be readily appreciated that any listed range fully describes and divides the same range into at least equal halves, three parts, four parts, five parts, ten parts, etc. As a non-limiting example, each range discussed herein can be easily broken down into a lower third, a middle third, and an upper third, and so on. Those skilled in the art will also understand that all language such as "up to," "at least," etc. includes the recited quantity and refers to ranges that can then be broken down into sub-ranges as discussed above. Finally, as will be understood by those skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 units refers to groups having 1, 2 or 3 units. Similarly, a group having 1-5 units refers to groups having 1, 2, 3, 4, or 5 units, and so on.
上文公开的各种以及其它特征和功能或其替选方案可以组合成多个其它不同的系统或应用。本领域技术人员可随后做出对其的各种当前不可预见的或不可预期的替选方案、修改方案、变型例或改进,其中每个同样旨在由公开的实施例所涵盖。 Various of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements thereto may subsequently be made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
